Purpose:

This test simulates the exposure of the component to splash water as it occurs when driving through puddles.

The test is intended to verify the function of the component when exposed to abrupt cooling by means of water.

Test:

Operating mode of DUT:

If the component is not operated with operating load in driving mode:

II.a during the entire test

If the component is operated with operating load in driving mode:

Intermitting II.a and II.c during working condition driving

Test procedure:

Heating of DUT to test temperature.

This is followed by the cyclic splashing of the DUT as per Figure 35.

The DUT shall be splashed over its entire width.

Introduction to structural design

1. The outer casing of the equipment is made of 2mm high-quality galvanized steel plate CNC machine tool, and the surface of the outer casing is sprayed, which is more smooth and beautiful.

2, the liner is SUS316 high-quality stainless steel mirror panel; in order to facilitate the recycling of the test medium and the cleaning after the Zui, the bottom of the equipment studio is designed as a funnel;

3, insulation material: high-density fiberglass cotton to ensure insulation performance, maintain indoor balance and stable temperature;

4. The door is provided with a transparent window for observing the change of the indoor sample, and the observation window is made of multi-layer hollow tempered glass;

5. The mixing system adopts long-axis fan motor and high-low temperature resistant stainless steel multi-wing impeller to achieve vertical convection vertical diffusion cycle, so that the temperature and humidity in the laboratory are uniform and stable;

6. Double-layer high-temperature resistant high-strength sealing strip is used between the door and the cabinet to ensure the sealing of the test area. The inner door material of the door is made of stainless steel, and the door handle is made without reaction, which makes the operation easier;

7. Test hole (left side of the machine) can be used for external test power cable or signal cable (100mm aperture);

8. The refrigeration system of the equipment is installed at the bottom, and the compressor is imported from Taikang brand in France to ensure the cooling effect and reliability.

9. The bottom of the machine is equipped with a high-quality fixed PU movable wheel, which can easily move the machine to the designated position, and fix the caster after the Zui;

10. The control part of the equipment is designed on the right side of the equipment. It is distributed with temperature controller and control switch. It is easy to operate, simple and easy to maintain.

 

Equipment use conditions

1. the ambient temperature: 5 ° C ~ +32 ° C;

2. Ambient humidity: ≤85%;

3. power requirements: AC380 (±10%) V / 50HZ three-phase five-wire system;

4.pre-installed capacity: about 3KW

5.4.2 Splash water test

 

5.4.2.1 Test method
Heat the DUT in a hot air oven at Tmax for the specified holding time,th. Then splash the DUT with ice water for 3 s. If the DUT is splashed in the vehicle from only one direction, splash it from this direction only while it is in an as-installed position. If the equipment is splashed from various directions in the vehicle, then these directions shall be taken into account. In this case, use a new DUT for each splash direction. The width of the splash directed at the DUT shall always be greater than the width of the DUT. If the DUTs to be splashed prove too big for one jet, arrange several jets in a row to produce a line of splash impact on the DUT. See Figures 4 to 6.

 

Test parameters include:
⎯number of cycles: 100;
⎯holding time,th, at Tmax: 1 h or until DUT temperature stabilization is reached;
⎯transition duration:<20 s (for manual transition of DUT between temperature storage and splashing);
⎯test fluid: de-ionized water;
⎯water temperature: 0 °C to +4 °C;
⎯water flow: between 3 l and 4 l per 3 s (splash duration);
⎯distance between jet and DUT surface: (325±25) mm (water shall be applied over the complete width of the DUT);
⎯operating modes: see Figure 5;
⎯orientation of the DUT: as in the vehicle.
